MLSMITH83 is right, get a FAN COOLED 2 up sled (likely pre 2001) with REVERSE...ideally push button electronic reverse. Liquid cooled sleds need to throw snow up into a radiator like part that is above the track. No snow, no cooling the liquid running through that radiator back into the engine. Light array of studs is good idea too.
I like his idea of the dish soap to keep the slides cooler when no snow, will adopt that one.
